Be it known, that I, PAUL BAL,'.lHAsan 'i Wnrs,a" citizen of the `United States, and a 'residentof Aurora, in the'-county of Kane and State'of Illinois,vhave invented certain new anduusefull Improvements in Folding- DoorI-Ianger Equipments, of which `the :fol-

is employed for-the; doonupongfwhich runs v a` hanger,securedtofair-innerV leaf of the door so that jas it is opened and j folded, the hanger moves Vv'from' Itheyinner to `,the outer end of theftrack, thus` permitting' thepdoor" to open and relieving therackinggstrain on; thehinges.` 4'Prior tomylinventlomv so farV as I am aware,these supports were of'. two'v i: In the older-type,-

track was directly v line7-'-7 of Figpguand y above andparallelctothe `doorszwhen-they were closed, but this. location ofthe tracks had the objection that althoughivthel doors could be opened` and folded, they-could not beswung out of the` doorway,and-this necessitated employing an "unnecessarily widey doorway to get the desired yeffectivewidth'.V

In a later type developedto overcome this objection, theitracks lwereplaced outside of ,y the doorway and atan angle to the doors i in their closed position so that they` could f be, opened,folded 4and swung entirely out-- side of the doorway.` This type is open to the very serious objection that the position of the outer end of the tracks has to be carefully adjusted for different thicknesses of Y doors, or the number of the leaves of the door, or for varying positions to which the folded and open doors are iinally swung.

By my invention, I obviate the difficulties of both of these old types byplacincgl the hanger track outside of the doorway an parallel to the door, and employing atransv verse track upon which the outer end of the i hanger track moves when the door is opened and folded so that no adjustment whatever is required as the` outer end of the hanger trackl automatically moves out on the transverse trackwhen the door' is opened .and folded just as far as'. may be necessary and without having totake `into Vconsideration either the thickness of the door, the number and open door is linally,` swung.

of leaves, or the position tov which the folded.

In the drawings,I have indicated the eus tomaryside wallsflO and ceiling .11 `of a so 'Y room diagramma-ticall together @with` the .Y

VNear :the inner edges of the inner leaves 121 are the brackets 18v secured by the bolts 19 and having theV hangers 20fadjustably mounted thereon in Vthe customary manner so that the wheels 21 of Athe hanger may `center' `accurately on the track flanges 22 of the customary-track 23, which is pivotally supported at its inner end by the yoke 24 in bolt 25 to the ysupporting bracket`26 secured i to the end wall 12fabove the doorway 13.

AThe outerl ends of thetracks 23 havejsevof? ` which it is securedr'which is pivoted by the cured thereon the sockets27, whichr are pro-l i Vvided with the outwardly projecting ,ax1e28 `for the grooved roller29` mounted thereon to coperate with the` transversey track 31k whichmaybe convenientlymade of .a bar ci iron having the track proper standing' ver tically and the securing web 32 twisted at L right yanglesv thereto and secured by the lsrews' t0 the Wall The socket 27 isf 66 and: in their Vopeniposition in dotted lines;

provided with a flange 3()V extending under the track 31 so as to prevent the roller 29 from being, lifted off of the transverse trackl Sl'during its movement thereon. This track 31 1s curved on the arc of a circle of which the bolt is the center, and its main por-A tion is preferably inclined downward slightly from the outer to the inner end so that when the door is closed, the roller 29 will tend to move by gravity back to the normal full line position shown in Fig. `2 where the track Vis parallelto the closed door. To brace the transverse track 31, I ,form on the upper end of the' web 32 the offset eye 34 lthrough which passes the braceV rod or bolt 35, the lower end of whichpasses through an aperture in the twisted an-d turned up end 36 ofthe transverse track 31 and is secured thereto by a nut.

VThe operation of my improved. support will be readily apparent. When the doors are closed, the tracks 23 are in the full line position shown parallel to the closed'doors, and as the doors are opened and folded the hangers 20 run out in the tracks 23, which swing out Vto the dotted line position shown in Fig. 2, and which position will be just as far as is necessary to accommodate the opened and folded doors, irrespective of their thickness, the number of leaves or the A position to which they are moved, To illustrate this, the door on the right hand side of Fig. 2 is shown as opened less than the door on the yleft hand side with the result that the cooperating track 23 is not swung out so far as is the track 23 on the other side. lhen thedoors are closed, the tracks swing backto their' normal parallel position, and it will be obvious that in equipping` folding doors with these supports, it is not neces.- sary to supply various sizes of the transverse tracks or make any adjustment therein, as all that is necessary is to mount the invention as embodied in the Vform which lV v at present consider best adapted to carry out its purpose, it will be understood that it is capable of modifications, and that do not y desire Vto be limited in the interpretation of the following claims except as may be necessitated by the state Vof the prior art." Y

fhat I claim as new, and desireto secure by Letters Patent of the United Sta-tes is 1'. ln an apparatus of the class described, the combination with a hanger secured to a door, of ahorizontal track therefor pivota'lly supported at its inner end, an antifriction roller mounted on the outer end of said track, and a curved transverse track upon whichthe roller runs as the horizontal track swings outward when the door is folded and opened. i

. 2. In an apparatus of the class described,

the combination with a hanger secured to a door, of a horizontal track thereforrpivctally supported at its inner end, an antifriction roller journaled on the outer end of said-track, a curved transverse track upon which the roller runs as the horizontal track swings outward wnen the door is folded and opened, and a flange projecting` from the outer end of the horizontal track beneath the transverse track.

ln witness whereof, I have hereunto set my hand and affixed my seal this sixth day of February, A. D. 1919. Y
